PMP-Based Micro-3D Dental Measuring Technology

Abstract:

Based on the structured light measurement principle, digital fringes projection technology and phase-shifting measuring technology, specific to the 3D profile of some tiny objects like teeth, in this paper we proposes a 3D scanning system which was directly used for intraoral dental measurement utilizing the merits of flexible and long distance signal transmission of the fiber image bundle. The structured light is projected out from DLP LightCommander produced by Texas Instruments Company, shrunk via telecentric imaging lens, conveyed in fiber image bundle. Utilizing the transformational relation between single-camera and projector, afterwards, the 3D profile of teeth is obtained by reconstructing the acquisition images in electronic endoscope. The feasibility of this system has been testified in our experiments. It satisfies the requirements of miniaturization, directness and flexibility; expands the scope of application of micro-3D measurement with structured light in dental clinical practice.
